Which of the systems above could not be detected using the transit
method?
While doing a transit study, you find an exoplanet around a nearby Sun-like star. The time between transits is P= 32days. During a transit, the time from first to second contact is t2−t1= 30minutes, and the time from fist to third contact is t3−t1= 5hours. The depth of the transit is δF/F= 0.01. During follow-up radial velocity measurements of the star, you find that its peak radial velocity is vr= 65m s−1. What is the radius of the planet? What is the mass of the planet? What is the semimajor axis of the planet’s orbit?
Use this light curve of a star with a transiting exoplanet to answer the following. If the exoplanet is orbiting
a star identical to our own Sun, what is its average orbital distance, in AU? What is the period in years of
the transiting exoplanet?

- H5. A star with mass 1.05 M has a luminosity of 4.49 × 1026 W and effective temperature of 5700 K. It dims to 4.42 × 1026 W every 1.39 Earth days due to a transiting exoplanet. The duration of the transit reveals that the exoplanet orbits at a distance of 0.0617 AU. Based on this information, calculate the radius of the planet (expressed in Jupiter radii) and the minimum inclination of its orbit to our line of sight. Follow up observations of the star in part reveal that a spectral feature with a rest wavelength of 656 nm is redshifted by 1.41×10−3 nm with the same period as the observed transit.
